Summary: A facile method based on hydrogels and ceramic nanofiller is proposed to fabricate composites with post-tunable mechanical properties. The wide tunable range of Young's modulus and ultimate stress can be achieved by combining solvent absorption and evaporation process with platelets reinforcement effect. The introduction of a nacre-like brick and mortar structure results in a large fracture toughness. The material demonstrates superior flexibility and designability.

Summary: Natural biomaterial bamboo exhibits excellent strength and toughness, which are influenced by the content and tensile strength of fiber bundles within the bamboo wall. This study found that bamboo loaded from the inside showed higher flexural strength, toughness, and bending fracture energy compared to bamboo loaded from the outside. Radially loaded samples demonstrated intermediate mechanical properties. The fracture behavior included parenchyma fracture, fiber fracture, and interfacial debonding, while cell wall tearing, fiber debonding, fiber bridging, fiber pull-out, and crack deflection were identified as the major fracture-toughening mechanisms.

Summary: This paper analyzes the types and basic properties of fibers to enhance the toughness of geopolymer concrete, summarizes the advantages and disadvantages of different fibers used as a material to enhance the toughness of concrete, and reviews the effects of fiber type, shape, volume rate, aspect ratio, and hybrid fiber combinations on the static mechanical properties. The results show that fibers have significant potential to enhance the mechanical properties of geopolymer concrete, and the optimal fiber volume rate seems to be related to the fiber type. The influence of aspect ratio and hybrid fiber combinations on the properties of geopolymer concrete is also apparent. This paper provides a solid foundation for the further development and application of fiber-reinforced geopolymer concrete and offers recommendations for future research.

Summary: Preterm birth affects 10% of pregnancies worldwide, with the majority caused by rupture of the amniotic sac. This study examines gelatin membranes as potential materials for patching fetal membranes in medical interventions. The researchers found that stiffness was not affected by crosslinking, but failure strength varied. Compared to natural amnion, electrospun materials were stiffer and stronger but less fracture resistant. Further research is needed to understand the structure-properties relationships in fibrillar materials.

Summary: This study investigates the effects of exposure to medium-high temperatures on the mechanical properties of quartz fibers. While temperature-induced strength reduction occurs, no significant changes are observed in bulk properties such as Young's modulus, density, and fracture toughness. Failure originates from the fiber surface, and the mechanisms involved may be related to the development of surface flaws.

Summary: This study investigated the effect of multi-scale structure characteristics on the mechanical behavior of horn sheath in different goats. The conformation of keratin and strength of fibers were found to significantly influence the tensile/flexural performance of the horn sheath under both dried and hydrated conditions. The corrugated lamellae structure was identified to promote crack deflection and enhance the performance of dried samples, making them more advantageous for flexural loading applications. The synergism of multi-scale mechanisms was found to be crucial to the mechanical properties of the Caprinae horn sheath.

Summary: Natural fiber-reinforced biocomposites with excellent mechanical and biological properties have attractive prospects for internal medical devices. However, poor interfacial adhesion between natural silk fiber and the polymer matrix has been a disturbing issue for such applications. In this study, rigid-flexible agents, such as polydopamine (PDA) and epoxy soybean oil (ESO), were introduced to enhance the interfacial adhesion between Antheraea pernyi (Ap) silk and polycaprolactone (PCL). The Ap-PDA-ESO strategy exhibited a greater enhancement in interfacial adhesion, and proposed interfacial toughening mechanisms.

Summary: In this study, we investigate the tensile and fracture behaviors of natural silk fibers with hierarchical structures and defects, and reveal their self-tolerance and fracture mechanism. By introducing transverse notches, we demonstrate that the silk fibers can effectively blunt the notches through longitudinal cracks, leading to ductile failure. The tensile behavior of the notched silk fibers is mainly determined by the magnitude of longitudinal crack and the interface interaction between nanofibrils.

Summary: This paper investigates the tool-ply friction behavior of jute/PLA biocomposites in thermoforming. A pull-through friction testing device was developed to characterize the tool-ply friction behavior of jute/PLA prepreg at elevated temperature. The effects of alkali treatment, fiber orientation, normal force, and slipping velocity were studied, and a quantitative definition of tool-ply friction behavior was achieved. The results indicate a strong relationship between tool-ply friction behavior and woven and fiber structures, indicating hydrodynamic lubrication.

Summary: Micro-arc oxidation (MAO) treatment was used to modify aluminum (Al) alloys in order to improve bond strength with carbon fiber reinforced polymer (CFRP). The treatment successfully created a porous surface with better hardness, roughness, and wetting, and introduced resin pre-coating (RPC) and carbon nanotube (CNT) fiber bridging to improve the bonding interface. The combined treatments significantly increased the bond strength by up to 156.1%, indicating the feasibility of MAO as an alternative method for manufacturing high-performance Al-CFRP composites in industrial production.
